TLC: xml.expat 1.0-alpha available for ACL5

This distribution contains a package of Allegro Common Lisp FFI routines and Common Lisp wrapper functions which allow James Clark's expat XML parser to be used from Common Lisp. It also contains portions of the expat source distribution (dated 19991013) which I have modified to build shared libraries suitable for foreign-loading on Unix systems. [Note that this has been tested only on Intel Linux and Sparc Solaris to date.]

This alpha release should be considered a work-in-progress. I'm putting it out in its current state primarily to solicit feedback on the Lisp interface I've designed.
